Hogwarts: I rely on MC to pretend to be an alchemy professor

"You are such a gentle person... I almost want to come back to life and take your class." Myrtle slowly retracted her body into the toilet, leaving only her head exposed.

"Thank you for your trust, really."

"You are very polite. Why did you come here to see me? I don't believe that anyone would visit a ghost for no reason." The two braids swayed like water plants in the water.

"My question is a bit offensive, you may be angry when you hear it."

"Since you are so polite, I can forgive you once, ask."

Kaysen nodded: "How did you die?"

Myrtle seemed to be relieved when she heard this question, and Kaisen only heard a long tail sound.

"This question is not offensive. For me, death is like a second life, like a birthday, and it is worth celebrating."

"Then I am lucky. I chose a good question."

"Well... when I died, an annoying guy laughed at me. I don't know where she is now. Maybe she married a troll, or maybe she choked to death while eating a bagel that day. Anyway, I wish her a bad life with my magical heart."

"I cried here that day, in this bathroom, until I heard a boy's voice. It sounded pretty good, deep and magnetic. I think the owner of that voice should be a handsome guy."

"It's a pity that the occasion is not right. After all, This is actually the women's bathroom. I turned around to remind him, and then I died. "

Kaysen touched his chin...

"That's all?"

Myrtle nodded: "That's all... not all. At that time, I also saw two yellow-orange... eyes like some giant creature."

"This clue is very useful. Also, how did you die? What did your body look like?"

"Just like that, peaceful and scary, like sleeping. I would rather die ugly, because that would scare that guy a little harder. If I die as scary as Bloody Baron or Sir Nick, that guy will definitely not be able to hold on!" Myrtle said with some regret.

"That guy?"

"It's the annoying guy who laughed me into this bathroom as I said at the beginning."

"That guy is..." Kaisen asked curiously.

"I won't tell you her name. Maybe she died in some unknown corner a long time ago. I just hope her name can completely disappear from this world." Myrtle said viciously.

"Well...I understand."

"Can I ask you why you ask this?" Myrtle asked again.

"To find out the truth about your murder, find the murderer, and protect the young wizards now." Kaisen explained.

"Well...you are a good person, and your actions are worthy of this face..." Myrtle smiled and stared at Kaisen.

"Oh...thank you for the compliment."

"You're welcome, just like you are complimenting me. If you want to hear this kind of naked compliment, just come here."

"Thank you, I will if you need me."

After getting the answer, Kaisen said goodbye to Myrtle politely and enthusiastically, which could be called a step-by-step look back. Of course, apart from the farewell, there was no other extra gaze on any part of the bathroom.

After all, the doorplate outside the bathroom said female, and it was unreasonable for him to come in by himself, and scan every inch of the bathroom carefully like a staring frame...a bit perverted.

After returning to the office, Kaisen pulled a small mobile blackboard from the classroom downstairs and placed it in the corner of the office area. He wrote two key points on the front with chalk. One was the huge yellow eyes, and the other was the intact body.

Drawing these two key clues that can be confirmed on the blackboard, the other clues found later were applied to it like a formula. It was quite convenient, but the neighbor was full of contempt for this stupid method.

".................If that guy was a wizard, I would still be staring at the damn blackboard..." Kaisen leaned on the armchair and muttered from his lips.

The next day..................

"Class is over." After saying that, Kaisen picked up a few draft papers on the podium, knocked the four corners, and then casually folded a thick paper airplane and threw it into the trash can.

The Ender teleported directly to Hagrid's villa next to the Forbidden Forest.

If you want to find someone who knows the most about magical animals in Hogwarts, the first person you think of is definitely Professor Kettleburn, the professor of magical animals.

However, this professor has a quality that makes people can't help but praise him. In seven days a week, he uses one day to complete five classes for five grades, and the remaining six days are spent wandering around the world.

So that.............can't find it.

But it doesn't matter. If Professor Kettleburn can't find it, there is another person who knows magical animals.

"Knock knock knock!"

After a while, Hagrid, wearing an apron, opened the door.

"I'm baking a small cake, come in and try it. Of course, I'll be happier if you can take some away." Hagrid hurriedly welcomed Kaisen in.

Kaisen, who was sitting on the sofa...............

Chew, chew, chew.......................

"Hagrid, do you know tires?"

"Yes, what's wrong?"

"A tire that tastes like cake, or a cake that tastes like a tire, which do you prefer?" Kaisen asked.

"...................................."

"Are you really starting to study it?"

Hagrid blushed after hearing this, and took the cake off the coffee table without a word.

"Maybe something else, rock cake."

"I want milk too."

"Of course, I won't forget the milk."

Soon, after changing a set of tea snacks, Kaisen let out a long breath. He couldn't help but think of the three-headed dog last year. Maybe the big guy's teething toy was the cake made by Hagrid.

Not to mention the taste..............at least it tastes good.

"Well, the new year has begun again...To be honest, I think the sun is even brighter in this Black Lake." Hagrid sat on the sofa and sighed at the Black Lake in the distance through the window.
